Who would you say is Spiderman's number one foe? I have a couple of thoughts.

I want to say Green Goblin. He killed Gwen Stacy and has been messing with Spiderman/Peter Parker for years. He has truly put him through Hell.

But then again Doc Ock stole his body and became Peter for awhile and almost erased Peter Parker from existence. I would bet that had to be pretty traumatic for a guy to go through.

So who would you rank as Spiderman's biggest foe?
